s2: and entering an experiment operation module according to the experiment simulation task to simulate the satellite attitude and the orbit in different scenes. The UI interface is provided with jump keys among different scenes, and scene switching can be performed in a mouse clicking mode;
scene one: in a space environment situation analysis scene, in order to obtain the maximum accuracy of the operation information of the satellite, the position information of the satellite is prestored in a format file, and the related information conditions of the satellite and the orbit are obtained in a mode of decoding and loading the file through a C # script. The first scene can realize special customized display of different satellite constellations and real-time display of specific parameter information of all satellites in the constellations, so that a user can clearly analyze and know the operation situation of the whole satellite constellation.
Scene two: in the virtual simulation scene of satellite orbit principle, in order to guarantee orbital specification display, used a plurality of orbital different parameters of portrayal to go the drawing orbit, include: the major half axis, the minor half axis, the inclination degree and the like of the track, and each parameter is subjected to fault-tolerant processing, so that the basic correctness is not ensured even if the parameter input by a user is too large or too small, and the condition that the display is not met due to exceeding the limit can not be generated. The method is realized by obtaining the most suitable and vivid data range control through a plurality of attempts to satellite orbit data and correspondingly judging the size of input data of an input box. In addition, in order to enable a user to observe the operation effect of the satellite more clearly, a sliding strip capable of adjusting the operation speed of the satellite is arranged on the UI, and the rotation of the satellite can be accelerated and decelerated by adjusting the sliding strip.
Scene three: in a satellite earth observation task scene, in order to better view a satellite observation angle, dynamic projection of a satellite carrying camera is adopted and dynamically displayed on a screen in a small window mode, and for the imaging effect of the satellite observation angle on the screen, a Unity engine self-carried layer imaging and covering function is adopted, so that the satellite earth observation task scene is reasonably displayed at the corner of the screen in a small window mode, the condition of displaying in windows with different resolutions can be fully considered, and when the window is enlarged, the projection can be properly increased and reduced.
In order to enable a user to have a better observation effect, the illumination of light is realized when the satellite sweeps the ground, and the user can be intuitively reminded that the satellite is observing. Secondly, in order to make the user know that the satellite scanning process is not a single one-time sweeping process but three-time landmark scanning effect, three scanning areas with different colors are placed on the ground, and each scanning area has ten sub-areas. Each time the scanning is carried out, a landmark area with different colors is dynamically displayed. This is achieved by detecting the position of the satellite, and by using a timer to display the sub-regions in sequence when the satellite is over the defined position.
And for the adjustment of the satellite observation angle and the satellite speed, the value of the UI slider is dynamically acquired through the C # script, and then the camera and the satellite are adjusted in real time.
Scene four: the gravity and gravity simulation module embedded in the Unity engine simulates the gravity between the satellite and the earth, so that momentum conservation of the satellite in the process of rotating around the earth is realized, and the acceleration and deceleration processes of the satellite and the observation of the subsequent orbit change condition of the satellite can be simulated by providing a forward and reverse speed increment process for the satellite in the normal in-orbit operation process of the satellite.
And adopting Token to carry out identity authentication, when the front end uses a user name and a password to request authentication from the server, if the authentication of the server is successful, returning the Token to the front end, and the front end takes the Token returned by the server to prove the legal status of the front end when requesting. For example, after a user name and a password are logged in a webpage, all front-end pages submit input contents to the back end of the system in a form to search and compare, and check whether the user information exists in the database, while the token is responsible for carrying account and password information to the back end, and the authentication class defined in the back-end code can complete identity authentication. The main part of this authentication class is implemented by code.
